Which wires give constant, ignition and ground on a 2025 Ford F-150?
On a 2025 Ford F-150, take constant power from the Brown/Red wire at the OBD-II port or the gray 30-pin plug at the driver kick panel, ignition from the interior fuse panel (wire color not published), and ground to the Black/Gray wire at the OBD-II port or the gray 30-pin plug at the driver kick panel. Meter every wire first.
Meter every wire before you tap it. Colors change with trim and build date.

Where do I get constant, ignition and ground on a 2025 Ford F-150?
Constant and ground colors are the same on key and push-button trucks. No ignition wire color is printed, so use a fuse tap for switched power.
Option 1 Constant and ground
Driver side
Fortin draws the OBD-II port and a gray 30-pin plug at the driver kick panel.
Constant
Brown/Red

The guide does not say which of the two plugs holds each wire. Find the color and meter it.
Option 2 Ignition
Fuse tap
For switched power.
Ignition
Fuse tap
Interior fuse panelNo ignition wire color is printed for these years. Meter the slots with the truck off, then on, and use an add-a-fuse tap.
Pick a slot that is dead with the truck off and hot with it on. Ford renumbered the fuse panel for 2024.

This page covers the 2025 Ford F-150 with a gas engine, key start or push-button start.
The wire colors come from Fortin's install guides, read wire by wire. Fortin works this truck mostly over the data bus, so only a few plain wires are printed. Our own team has not yet metered these on a 2025 truck.
Written by API Signal, fleet GPS and camera installers for 35+ years across Georgia, South Carolina and North Carolina, installing every major telematics and camera brand. Every wire on this page lists its source.
Test every wire with a meter before you tap it
No wiring information is ever guaranteed. Colors and locations change with trim, options and build date, and the manufacturer can change them in the middle of a model year. We share this as a starting point for installers, and you are responsible for confirming every connection on the truck in front of you.
